Specific embodiment
Technical solution of the present invention is further shown below with reference to Fig. 1 and Fig. 2, specific embodiment is as follows:
Embodiment one
A kind of emergency automatic control immersible pump, including immersible pump 1 are present embodiments provided, the water outlet 2 of the immersible pump 1 passes through
First flow monitoring unit 3 is connect with drainpipe 4, and temperature monitoring unit 7, institute is arranged in the immersible pump 1 at motor bearings 6
4 port of drainpipe setting second flow speed monitoring unit 5 is stated, setting offset monitoring unit 8, described first-class on the immersible pump 1
Slowdown monitoring unit 3, second flow speed monitoring unit 5, temperature monitoring unit 7 and offset monitoring unit 8 are connect with control unit 11,
The immersible pump 1 is connect by solid-state relay 12 and circuit protection unit 13 with power supply 14, described control unit 11 with it is described
Solid-state relay 12 connects.
First flow monitoring unit is monitored the ponding flow velocity that immersible pump is discharged, and the power of immersible pump is certain, row
Ponding flow velocity out can be set, and when the speed that water is discharged is significantly less than the flow velocity of setting, may be blocked in water inlet,
Motor rotation can be driven in the reverse direction by control unit at this time or is shut down the several seconds, tamper is pushed open, it will if it still can not solve
Tamper is removed in immersible pump taking-up.Second flow speed monitoring unit measures the ponding flow velocity at draining pipe port, when it
When the flow velocity measured less than the first flow monitoring unit, illustrate that drainpipe occurs leaking or drainpipe and the first flow monitoring list
Member leaks, and two values difference is larger, needs to overhaul equipment.Temperature monitoring unit carries out the bearing of motor
Temperature monitoring, the grease lubrication performance at bearing is poor when the temperature is excessively high, needs to add or replace lubricating grease.Offset monitoring
Angle, position and Vibration Condition after unit can place immersible pump are monitored, and are placed immersible pump and are toppled over, fall into soil
It is interior, and the working order in immersible pump is monitored, immersible pump can influence its quality of drawing water when ponding is less after toppling over,
Dell can be formed in the place drawn water by falling into soil, and unnecessary silt extraction amount is increased, the difficulty of work is increased,
And the pump housing vibrating numerical it is larger when, intracorporal mechanical part is pumped when more than 4mm/s and is likely to occur damaged condition, is needed to the pump housing
Maintenance or replacement.Control unit is connect with each monitoring unit, and the information monitored to it handle and by solid-state relay
Device controls the switch of immersible pump, forms the operating system of a closed loop, immersible pump can be allowed to run in the case where guaranteeing safety,
The urgent and uncomprehending drainage works of ponding environment can be coped with.Circuit protection unit protects immersible pump, as electric current is prominent
When so increasing and being more than the safe current of immersible pump, control circuit is disconnected, and closes immersible pump；Such as implement electric leakage to immersible pump to protect
Shield.The life security of staff is ensured.
The first flow monitoring unit 3 and second flow speed monitoring unit 5 are all made of electromagnetic flowmeter.Electromagnetic flowmeter is answered
With electromagnetic induction principle, conductive fluid flow is measured by the electromotive force inducted when externally-applied magnetic field according to conductive fluid, in cross
The flow velocity of fluid can be measured in the case that section is certain, the ponding flow velocity of discharge can be measured.
The temperature monitoring unit 7 includes patch type temperature sensor, and the temperature which is exclusively used in body surface is surveyed
It measures, motor can drill out screw hole, by patch type temperature sensing in rotation draining rapidly on bearing when at immersible pump at work
